摘要:
为了改善锌掺杂铝酸镁透明陶瓷的光学性能,优化放电等离子烧结技术的工艺条件,采用正交试验法系统地研究了锌掺杂浓度、烧结温度和保温时间对锌掺杂铝酸镁透明陶瓷直线透过率的影响，并利用扫描电子显微镜、双光束紫外分光光度计和傅立叶红外光谱仪等对样品进行了结构表征和性能测试.结果表明，放电等离子烧结锌掺杂铝酸镁透明陶瓷的最优化工艺条件为：锌掺杂浓度1.5%(原子百分比,下同)，烧结温度1 325 ℃，保温时间10 min.该条件下制备样品在波长550 nm和2 000 nm处的直线透过率分别为61.8%和80%.分析表明,影响可见光透过率的最主要因素是烧结温度，锌掺杂浓度和保温时间的影响较小; 工艺条件的变化对样品红外透过率的影响较小.
Abstract:
To improve the inline transmission of Zn∶MgAl2O4 transparent ceramics and optimize the sintering parameters by Spark Plasma Sintering(SPS), the orthogonal experimental design method was applied to study the effects of sintering parameters including Zndoped content, sintering temperature and holding time on the optical property of Zn∶MgAl2O4 transparent ceramics. A scanning electron microscope(SEM), a doublebeam Ultravioletvisible(UVvis) spectrophotometer and FTIR/Raman spectrometer(FTIR) were used to characterize the microstructure and optical properties. The results show that optimum process conditions of SPS are Zndoped content of 1.5at% (atomic percent), sintering temperature of 1 325 ℃ and holding time of 10 min. Furthermore, the inline transmission at the wavelength of 550 nm and 2 000 nm is 61.8% and 80%, respectively. The main significant factors which effect on the visible light transmittance are sintering temperatures, the doping concentration, the holding time has less influences on the visible light transmittance. In addition, the changes of sintering parameters have little influences on infrared transmittance.
